Abstract

A flashlight (10) is described that includes a chamber (20), end cap (30), head assembly (40) and lamp holder assembly (50). The end cap includes a bowed tripod portion to facilitate standing the flashlight on a flat surface. The head assembly includes a reflector and a lens. In one embodiment, the head assembly includes an elliptical reflector. In accordance with another embodiment, the flashlight having an elliptical reflector is matched with a negative or planar lens. In accordance with another embodiment, the head assembly includes a hyperbolic reflector. In accordance with another embodiment, the flashlight having a hyperbolic reflector is matched with a positive or planar lens. In accordance with another aspect, the flashlight includes electrode connections, which prevent the conduction of electrical energy from batteries that are improperly aligned within the flashlight. In another embodiment, the lamp holder assembly includes a lamp socket having a lamp guide, which provides a guide for installing lamp bulbs into the lamp socket and also provides a secure position for the lamp bulb. In another embodiment, the lamp holder assembly further includes a fluorescent coating or additive which illuminates light in otherwise dark conditions, thereby facilitating lamp replacement in the less than desirable light conditions. In another embodiment, the flashlight comprises a head assembly attached to the chamber, which is rotatable relative to the chamber to cause electrical coupling of a lamp and one or more batteries retained by a chamber. In another embodiment of the flashlight, the spare lamp is held secure by the lamp holder assembly until the user of the flashlight rotates the lamp holder assembly to align a spare lamp opening with the spare lamp.
